Growing basil in a hydroponic system is an easy way to have a fresh supply year-round, especially if you have little space for a garden. The flavor of hydroponically grown basil is the same as that of basil grown in soil. Basil is easier to grow in a hydroponic system with starter plants from a nursery. Hydroponic garden systems can be purchased online or at most local garden centers and are simple to set up.
Choose your hydroponic grow system. There are a variety of systems available for hydroponic growing. The two recommended systems for growing herbs are nutrient film technique and deep water culture. Both systems suspend the plants in nutrient solution. Nutrient film technique circulates the solution around the roots of the plants. Water culture technique involves suspending the plants while an air pump and air stone work together to keep the solution oxygenated.
Install your hydroponic grow system in a permanent location. This can be in your home, in your basement or in a greenhouse. Install grow lights to ensure that there is enough light for the plants year-round.
Remove the seedlings from the pots. Gently wash the roots of the system under cool water to remove all soil. Insert the basil seedlings into the hydroponic grow system.
Maintain the pH balance of the nutrient solution. The solution should be 6.5 pH. Check the levels using a pH meter. Nutrient solution can be adjusted by adding additional nutrients.
Things You Will Need
- Hydroponic grow system
- Grow lights
- Nutrient solution
- pH meter
- Basil can be started from seed in a hydroponic system. Use rock wool in small net pots to start the seeds.
- Add nitrogen to increase the acidity. Conversely, add sodium bicarbonate to decrease the acidity.
- Change the solution out once every three weeks to prevent algae growth.
